PORTABLE ELEVATOR.

SPECIFICATION forming part of Letters Patent No. 558,829, dated April21, 1896.. Application led November ll, 1895. Serial No. 568,529. (Nomodel.)

T0 a/ZZ whom t may concern:

Beit known that we, MICHEAL MCGARTHY and JOHN l-I. WEHMHOFF, of DaltonCity, in the county of Moultrie and State of Illinois, have invented anew and useful Improvement in Portable Elevators, of which the followingis a specification.

Our invention is an improvementin that class of portable elevators thatare provided with tra1isporting-wheels and a platform, on to whichloaded wagons may be driven and then hoisted at one end for dumpingtheir load into a box that slides vertically and is adapted to be tiltedto discharge its contents.

In accompanying drawings, three sheets, Figure l is aside view of ourapparatus. Fig. 2 is a horizontal section, enlarged, of the main portionof the apparatus. Fig. 3 is a side view, enlarged, of the top portion ofthe apparatus. Fig. l is a vertical section of the apparatus. Fig. 5 isa horizontal detail section. Fig. G is a perspective view, enlarged, ofa portion of the hopper, showing the hinged discharge-spout open. Fig. 7is a perspective view of the saine parts, showing the spout closed.

The elevator-frame consists of two connected upright portions A and B,which are of unequal height, and a horizontal rectangular base composedof two parts C and D, which are arranged at different heights. The baseC D is supported at its ends on pivoted axles h b', having truck-wheelsc. Each axle is provided with staples or clips d for attachment of apole or tongue @for use in guiding Vthe elevator while moving it fromplace to place. The tongue e is provided with hooks c, and thus adaptedto be easily detached from one axle b and attached to the other t', asrequired for hauling the elevator with either end forward. One or bothaxles must be looked in position when the elevator is being hauled, andfor this purpose we employ stay-rods f, Fig. 4, which are pivoted to thebase-frame and whose free ends engageA staples or eyes g, attached tothe axles near their ends. The part A of the upright framework is formedof parallel posts h and top crossbars z', on which two pulleys 7c aremounted. A rope m runs on said pulleys and extends down to a shaft n,hung in bearings on the side of the base, and having'a cog-gear 0, thatmeshes with a pinion p on a crank-shaft q. A pivoted locking-'pawlengages said gear, as shown.

The rope m connects with the hinged bail r of a skeleton cage E, thatslides on and between the four posts of th-e frame part A. Vithin saidcage E is arranged a tilting box F, the same being supported andeccentrically hinged on a shaft s, that extends transversely of thelower portion of the cage E, and is iixed thereto, Figs. Q and 3. Theaforesaid bail r is detachably connected with the ends of this shaft Sand is held normally in vertical position by means of diagonal braces t,Fig. 3, pivoted, to opposite sides of the cage and engaging the bail atits joints, as shown. It is apparent that if the lower ends of thejointed bail-pieces be detached from the shaft s it may be swung backout of the way, for a purpose hereinafter stated.

The box F is held in normal horizontal position in the cage E by meansof a catch or locking device. The latter consists of a bar or button u,pivoted to the rear side of the box F and adapted to engage thehorizontal bars forming the adjacent portion of the cage E. Thenadjusted in vertical position, the device u holds or locks the box F inhorizontal position, and when turned it allows the box to tilt or dumpby gravity and thus discharge its contents. The box F is provided with ahinged discharge-spout Ir, which, when in raised position, forms also aportion of its side-that is to say, spout fu is hinged to the bottom ofthe box F, and when raised fits in the opening in the side of the sameand closes it. c

A locking device w, operated by a pull-cord 0c, holds the spout in itsclosed position. The sides of the box adjacent to the spout are in*clined outward to facilitate discharge of the load, as will be readilyunderstood.

A slatted removable incline y is provided at one end of the base C D anda hinged and foldable incline s at the other end. Tho

hinged portion of the latter, e, is supported when in use by blocks orother formof stay. On the side of the base of the elevator, opposite theraised platform D, are arranged a cog-gear o', pinion p, and crankshaftg', sim i- IOO lar to those before described, for use in elevating andlowering the box F. A rope m runs on pulleys 7c', mounted on cross-barsof the upright frame part ,13. The said rope m suspends a bar r', havinghooks r2, as shown.

The elevator is used as follows: The cage E and box F being elevated, asshown by dotted lines in Fig. l, a loaded wagon is driven up the incliney, beneath the cage E, and drawn onto the higher portion D of theplatform, the team proper being advanced so as to stand on the hingedincline e'. The cage E is then lowered, and the bail r detached from itsshaft s and swung back out of the way, as shown. (See Fig. 5.) The hooksr2 of the grapple and hoisting apparatus are then attached to thefellies of the front wheels of the wagon, and, the gearing o/ p q beingrotated, the front end of the wagon is elevated, thus causing itscontents to discharge into the box F. The cage E is then elevated andthe spout unlocked, and the box released to allow it to tilt and dumpits load into a granary or other receptacle.

It is apparent that the elevator may be easily hauled from place toplace and used for elevating grain or other commodity, whether receivedfrom a wagon or otherwise.

Having thus described our invention, what We claim as new, and desire tosecure by Letters Patent, is-

1. The portable elevator having a wheeled axle pivoted at each endthereof and provided with staples, or eyes, on their inner sides, and

hooks pivoted on the sides of the baseframe, and adapted to engage saidstaples, as shown and described.

2. In a portable elevator, the combination, with the verticalguide-frame h, and a cage, E, which is slidable therein, of Vthe box F,an axle supporting said box, which is eccentrically mounted thereon, anda button pivoted to the back of the box and arranged as shown anddescribed, whereby it is adapted to engage the frame of the cage, whenadjusted vertically, and thus holds the box in horizontal position, asspecied.

3. In a portable elevator, the combination, with the verticalguide-frame, a cage which is slidable therein, an axle arranged in thecage, a box mounted eccentrically on the axle, a bail adapted fordetachable connection with the ends of the axle, and braces pivoted tothe cage, and their free ends being jointed to the vertical sideportions of the bail, and means connected with the latter for hoistingthe cage, as shown and described.

4. In an elevator, the combination, with vertical guides, of a slidablecage, a box hinged therein, a bail which is detachable from the cage,and pivoted diagonal braces for supporting said bail in normal position,as shown and described.
